Abstract: An apparatus includes a tube having at least one flow outlet in communication with an interior of the tube. The apparatus includes valves for selectively connecting the flow outlet to one of a fluid return line and an inlet of a fluid pump. The apparatus also includes valves for selectively connecting the outlet of the pump to the fluid return line and closing the pump outlet. A method includes returning mud from a wellbore into a riser extending between the wellbore and a drilling unit on the surface of a body of water. Flow from a tube in the riser is selectively diverted to an inlet to a fluid pump or a mud return line extending from the tube to the drilling unit. When the flow is diverted to return mud flow in the riser is stopped above the tube. When flow is diverted to the inlet of the pump, the pump is operated to lift the mud to maintain a selected mud pressure in the wellbore.

Abstract: A system for determining annulus fluid volume in a well bore during a drilling operation, the system having a pressure wave generator positioned at the top of a well, wherein the pressure wave generator generates a pressure wave that propagates through the annulus fluid in the well; a first pressure wave receiver positioned in the annulus of the well to receive the generated pressure wave at a first time value; a second pressure wave receiver positioned in the annulus of the well to receive the generated pressure wave at a second time value; and a controller that determines a change in annulus fluid volume based at least in part on a phase shift between the received pressure wave at the first and second time values.

Abstract: A conduit forming part of a drilling fluid return path from a wellbore has at least one flow restrictor disposed on an interior surface of the conduit. A drill string is disposed through the interior of the conduit and has at least one flow restrictor disposed on an exterior surface of the drill string. The drill string is longitudinally movable through the conduit to enable placing the flow restrictor in the conduit, and the flow restrictor on the drill string at a selected longitudinal distance from each other.
